PATENT MANUFACTURE OF TOBACCO-POUCHES.

SPECIFICATION forming part of Letters Patent No. 385,628, dated July 3, 1888.

Application filed October 12, 1887. Serial No. 252,172.

To all whom, it may concern.-

Be it known that I, JAMES GEORGE INGRAM,

of Felstead Street, Hackney Nick, London,

Now the object of my invention is to entirely remove this objectionable feature by forming the pouch without anyjoin or seam therein..

I will describe my invention as applied to the manufacture of the Horsey pouch, such as represented in the accompanying drawings, in which Figure l is a side elevation or face view of the pouch. Fig. 2 is a vertical longitudinal section of the pouch in its extended or open position. Fig. 3 is a vertical section of the dippingmold and device for supporting the same. Fig. 4- is a side elevation of the same. Fig. 5 is a vertical section of a modified form of the mold.

For this purpose I form a mold, b, as represented at Figs. 3 and l, of any suitable metal or alloy, to the shape of the interior of the pouch, a, required to be produced, and I then, by the process of dipping the said mold 1) into a solution of india-rubber or of any desired india-rubbcr compound, produce on such mold a coating of any desired thickness entirely without seam. The corners of the pouch a are preferably strengthened by means of pieces, a, of india-rubber, or of india-rubber or other fabric, which may be applied to the moldb before commencing the dipping process, or may be placed in proper position alter a thin coating of india-rubber has been formed on the mold 0. Then, by the dipping or further dipping of the mold into the solution, the said strengtheningpieces are firmly secured in position either on the inside of the pouch or in- (X0 model) termediate of the thickness thereof. These strengthenirig-pieces may, however, be applied to the pouch after the same is formed on the mold.

\Vhen the desired thickness of india-rubber or of india-rubbcr compound has been ob tained upon the mold b, an opening, a is cut therein, so as to form the lips a a of the pouch, and the raw edge of the lip a is then strengthened by turning over a portion of the material forming the body of the pouch, or it may be strengthened in other suitable manner. The completed pouch is then cured or vulcanized in any well-known and suitable manner, after which the mold I) is removed from the pouch a through the opening a between the lips thereof.

The rubber solution or compound to form the pouch may be colored in any desired manner, or color maybe applied to the pouch a at any other stage of the manufacture.

To facilitate the manipulation of the mold b, a wire, 0, may be fixed in one end thereof, and the other end of such wire may be removably fixed to a board, d, by means of clamps (1, a number of such molds being preferably arranged on one board, by which. means they can be simultaneously dipped into the solution. On removal of the molds from the solution after each dipping process the surplus solution collected at the lower edge thereof is carefully removed, after which the molds are reversed in position by standing the board (1 on atable or other support, by which means the thick ness of the coating is equalized.

When it is desired to remove the pouch from the mold, the wire 0 is released from the clamp d and the pouch is drawn off the mold, the wire 0 passing through the small hole formed in the pouch thereby.

When using comparatively thick wires 0 to support the molds b, a hole is formed in one end of the pouch, which, if desired, may be stopped before submitting the pouch a to the curing or. vulcaniziug process. If desired, however, the construction of mold. represented at Fig. 5 may be employed in carrying my invention into effect. In this case asmall tube, Z), is cast within the thickness of the mold and from end to end thereof, and a countersunk hole, I), communicating with such tube 3/, is

made in the center of the mold. A very'thin supporting-wire, c, is then passed through the hole b and out through one end of the tube b. The ends 0 0 of such wire 0 are bent, as shown, so as to enable the mold to be suspended from a suitable dipping board or frame, a similar wire a being inserted from the other end of the tube 1), to enable the mold to be readily reversed in position when required. Then, when the pouch is completed, the wires 0 have their ends 0 out off, and are then pulled out of the mold, when it will be found that only very small and unimportant holes have been made thereby in the pouch.

It will be understood that other forms of tobacco-pouches may be manufactured in a similar manner to that above described.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what 1 claim is- 1. The process of manufacturing tobaccopouches which consists in dipping a mold into a solution of the pouch-forming material, forming the opening in said pouch, re-en forcing the corners of said opening, and subsequently removing the mold therefrom, as set forth.

2. The process of manufacturing tobaccopouches which consists in coating a mold with a solution of rubber or suitable. composition, incorporating reenforcing strips at desired 10- cations during the process of coating the mold, and subsequently cutting the mouth of the pouch between said re-enforce and removing the mold therefrom, as set forth.

3. The process of manufacturing tobaccopouches which consists in coating a mold of desired shape with a solution of rubber, incorporating reenforciug strips therein at suitablev locations, forming the mouth of the pouch between said re-enforcing strips, vulcanizing or curing the pouch thus formed, and subsequently removing the mold, as set forth.
